Pristine boot of Q130: hotpluged Huawei E1550 has 3 /dev/ttyUSB items
/dev/ttyUSB0 and /dev/ttyUSB2 return imediately with the blank line and OK but /dev/ttyUSB1 does not return for at least 4 minutes. I connect with /dev/ttyUSB0.

Both Net and LapTopBook are connecting fine on ttyUSB0 by pgprs-shell -connect with two telephone companies.
There seems to be no difference between ATZ and ATV1Z here but it seems that the output at ttyUSB2 differs each time :
sometimes many lines with ^BOOT \n OK
sometimes one line with ^BOOT \n OK
the next try no ^BOOT \n OK
and another try one A \n(\n) OK

I remasterd these two dpup-005 and they don't show the fourth ttyUSB3 ....

Barry,
Please note that the usb_modeswitch package includes a udev rule that creates symlinks to the ttyUSB ports that are likely to work. If multiple candidates are detected, your only task is to distinguish which is the full data port. My implementation merely picks one (now, the highest), but your new logic can make that decision. The symlinks are created regardless of the need for a mode switch, it appears to me. The rule:

Code:

# This adds a symlink "gsmmodem[n]" to ttyUSB ports with interrupt transfer;
# will work only with wrapper from 1.1.4 and above (otherwise ignored)
KERNEL=="ttyUSB*", DRIVERS=="option1|usbserial", PROGRAM="/usr/bin/tclsh /usr/sbin/usb_modeswitch_dispatcher --symlink-name %p", SYMLINK="%c"

"dispatcher --symlink-name" provides the ttyUSB port for the link.

Richard,
I don't know why, but this does not work for my Optus Huawei E160E modem. This is the only modem I have right now.

When I get my hands on more 3G modems, I will see if they create the links._________________http://bkhome.org/news/

First boot of luci_241 with E169 inserted.
/dev showed all three ttyUSB0,1 and 2 present.
/var/log/messages also reports that the option module had been installed.
Opened up the terminal and typed "modem-stats-c "ATV1Z" /dev/ttyUSB0" , response " command not found".
Does this command need the dev.sfs package installed to function?

Fired up PupDial and was pleasantly surprised to see that it was already set up on the ttyUSB0 port rather than the onboard dial-up modem.

some good news= i have connected by nokia e63 modem in pc suit mode my apn is tata.docomo.internet
but i cannot connected by 3g usb datacard of bsnl
wish i could connect by 3g usb modem as early as possible by help of u
i interested in connecting usb 3g because it give me speed of 2.5-3.6 mbs
hope u solve it...
Wary 500 rocks it detects 3G usb modem but fails to connect....
all other puplets,puppys r not detect it....
hope this will solves all issues in other new release...
